Item #2003 Mini Saw Blade 24T 3 1/2 inch made in the USA *MOST COMMON FOR THIS STYLE*

These are heavy duty 3 1/2 inch long blades. The 24T are best for thin metals. They are made from two metal types, the teeth are a harder material, which stays sharp longer. The body of the blade is a softer material which is less prone to break. Putting the two together makes for a very durable blade (bi-metal construction). They are heat treated and made in the USA.
